著名人工智能公司的领导者，包括 OpenAI 的 Sam Altman、谷歌 DeepMind 的Demis Hassabis 和 Anthropic 的 Dario Amodei，都对其人工智能技术在医疗领域的变革潜力表达了坚定的信念。
过去几章探讨了生成式人工智能如何改变研究、生物学、化学和药物发现。随着大数据的发展，谷歌、微软和 IBM 等大型科技公司开始在医疗保健领域投入巨资，利用人工智能提高医疗诊断、患者管理和整个医疗保健系统的效率。早期的成功案例包括人工智能驱动的医学成像、预测性疾病进展分析以及医院的自动化工作流程。如今，生成式人工智能继续推动药物发现和个性化医疗领域的创新。
谷歌通过其人工智能研究部门 DeepMind 和以健康为重点的计划，在将人工智能应用于医疗领域方面一直处于领先地位。谷歌健康部门致力于为医疗成像和电子健康记录（EHR）开发人工智能驱动的工具，而 DeepMind 则通过 AlphaFold 在蛋白质结构预测方面取得了突破性进展。2021 年，谷歌以 21 亿美元收购了 Fitbit，巩固了其在可穿戴健康技术和人工智能驱动的个人健康数据洞察方面的地位。
苹果公司也通过 Apple Watch 等设备进入了健康领域，从 Series 4 开始，Apple Watch 具备了经 FDA 批准的心电图功能。苹果还与斯坦福大学合作，在 40 万名 Apple Watch 佩戴者中开展了 Apple Heart 研究，以检测心房颤动。该公司的手表现在包括糖尿病管理功能，并在一些实体店销售 One Drop Chrome 血糖监测仪和配件。苹果公司首席执行官蒂姆-库克（Tim Cook）表示："如果你把视线拉远到未来，回过头来问，苹果对人类最大的贡献是什么？它将与健康有关。"
微软在医疗保健领域也取得了长足的进步。其云平台Cloud Azure已经成为医院和医疗机构的热门解决方案，为预测医疗和数据管理提供人工智能工具。微软的人工智能工具可以帮助医生分析患者数据，预测潜在的健康结果。此外，Microsoft Dragon Copilot 通过使用多种人工智能工具来增强临床工作流程，使医疗保健专业人员能够将更多精力放在病人护理上，减少行政任务。
亚马逊通过 Amazon Care 和 Amazon Pharmacy 等服务进军医疗保健领域。Amazon Care 提供远程医疗服务，为患者提供虚拟咨询，而 Amazon Pharmacy 则旨在让患者更容易获得药物。与谷歌和微软类似，亚马逊网络服务（AWS）也为医疗服务提供商提供基于云的人工智能工具，从患者数据管理到疾病爆发预测，都能提供帮助。
在 公共医疗保健领域，世界各国政府正在采用数据实践和人工智能来管理大量健康数据、优化医院管理并加强患者护理。例如，英国国家卫生服务局已采用人工智能工具，帮助进行从疾病诊断到有效管理病人记录的所有工作。人工智能驱动的预测模型帮助政府预测医疗需求、分配资源和应对公共卫生危机。美国国立卫生研究院在人工智能研究方面投入了大量资金，资助探索其在药物发现、疾病诊断和个性化医疗方面应用的项目。美国食品和药物管理局（FDA）在监管人工智能驱动的医疗设备和制定指导方针以确保其安全性和有效性方面走在前列。加拿大卫生研究院支持医疗保健领域的人工智能研究，重点关注医学成像、基因组学和人口健康。
